Whale Watchers in North Iceland Observe Slaughter

Around 100 tourists on a whale watching tour with Nordur-Sigling from Húsavík on Skjálfandaflói bay in northeast Iceland were in for a shock on Tuesday night when they observed a group of killer whales attack a larger minke whale, slaughter and eat it.

“No one was expecting to observe slaughter but we decided to follow this natural phenomenon because it is very unusual,” Heimir Hardarson, marketing director of Nordur-Sigling, told Morgunbladid, adding that the tourists, who were mostly foreign, had been very taken aback by the spectacle.

Tuesday was likely the first time that pictures have been taken of killer whales attacking a larger mammal in Icelandic waters. Killer whales are on top of the food chain of predators in the ocean and are sometimes called the wolves of the sea.

Killer whales are divided into two groups—which some say are two different species—one of which only feeds on fish and another which hunts mammals of all sizes. Until now, only the first group was believed to live in Icelandic waters.

“It was obviously very organized and not rushed at all,” Hardarson described. “They acted like those who are in power and the calves jumped around and played in the blood.”

Hardarson and his associates counted between 20 and 30 killer whales that participated in the attack. They were very coordinated; they had surrounded the minke whale and then took charge in turn.

Hardarson said the minke whale had been terrified. “It was so confused that it swam into the boat two times and one time it looked as if it was going to hide underneath it.”

The minke whale died after a heroic fight, Hardarson said, and then there was a great feast for the killer whales which shared their catch with every member of the group.

Killer whales are known to have killed great white sharks and blue whales, but they are not known to have attacked people.

Killers have whale of a time as numbers grow

Shetland Islands Killer whales have been schooling off Shetland in record numbers, with up to 100 spotted by scientists feeding together at one time.

The lives and activities of the orcas are being catalogued by Andy Foote of Aberdeen University and Volker Deecke from the St Andrews Sea Mammals Research Unit. Their study is identifying the movements and feeding habits of the whale pods and trying to find out why there appear to have been more sightings in recent years. Some are drawn into the islands to hunt seals. One was seen bearing a fresh scar, apparently after scraping over rocks.

While accompanying a local fisherman, Mr Foote saw 100 killer whales feeding together. He was also able to identify a whale as the same one that was photographed in 1991.

One of the more frequently seen whales is Bigga, who is 7m long and was named after an uninhabited island between Shetland and Yell, to which he bears a passing resemblance. He usually lives alone, although he is sometimes to be found with a pod of five, including Busta, the leader of the group, and Ossa, the smallest member, who is thought to be either the younger brother or nephew of Busta.

Lone orca may have joined pod

Numerous sightings of orca pods around Auckland have given researcher Ingrid Visser new hope that the juvenile whale relaunched at Takapuna will be found with a group, probably further north in Rodney.


Dr Visser says she had about 100 phone calls on one day.

The whales have been seen at Kawau Bay, Snells Beach, Milford Beach and North Head.

Despite dedicating a whole day looking for her in the Hauraki Gulf the young whale has yet to be found.

"We spent day to day going from subgroup to subgroup but no little orca."

Three were seen off Milford Beach at about 3pm last Thursday afternoon by Glenfield resident Peter Ryan.

He estimated they were about 200 metres offshore.

"I’ve never seen anything so close."

Mr Ryan says he saw two together and a third further out.

"One was very large, you could tell by the size of its fin. I’m guessing they were chasing stingrays."

Dr Visser says there are at least three different pods in the Hauraki Gulf and the juvenile could be among any one of them.

Another is reported to be on its way from the Bay of Islands.

"We haven’t seen her yet, but it doesn’t mean she hasn’t joined one of these groups."

Dr Visser says killer whales can hear each other from nearly 20km away underwater, which makes it easier for them to meet up.

Killer whale flips seals out of water with its tail


Just when the seals thought it was safe to go back in the water . . . along came Bigga
He's an adult male orca or killer whale, about seven metres from nose to tail, weighing probably more than five tonnes and with a dorsal fin almost as tall as Portsmouth's new striker Peter Crouch.

In captivity an orca needs to down a daily 45kgs, equivalent to a small adult common seal. The appetite of a sea-going wild adult is much bigger.

In Whales of the World (1981), Lyall Watson refers to a report of an adult male found to have parts of 13 porpoises and 14 seals in its stomach - and another seal in its throat.
So when Bigga cruised menacingly into South Nesting Bay about 10 miles north of Lerwick, capital of the Shetland Isles, the fear that gripped the local seal colony was palpable.

"They were very aware of his presence and sensed that they were his target", said Andy Foote, an Aberdeen University postgraduate researcher working on the Scottish Killer Whale Project.

"As Bigga cruised up and down very close, staying out of the sea was their best survival strategy. At one point we saw a female with her flippers protectively around her pup, seemingly trying to make sure it didn't panic and slip into the water."

But three hours of patience finally paid off for the huge predator. The watchers realised this when a cloud of blood appeared suddenly on the sea's surface, then there was turmoil as the remains of the pup Bigga had just seized were flipped into the air by a powerful swipe of his tail.

"Killer whales often play with their food in this way", explained Mr Foote. "We don't really know why they do that - it's one of many mysteries that surround these fascinating animals."

Examples of this behaviour are given in Whales of the World: "We have seen a group in the Galapagos dismember a five metre manta ray by throwing it into the air."

Getting to know individual killer whales is an important part of the project engrossing Mr Foote and his colleague, Dr Volker Deecke, from the Sea Mammals Research Unit at St Andrews' University.

Once an orca is identified via photo, it is given a number and a name. Bigga - named after a whale-shaped island between mainland Shetland and neighbouring Yell - is also known as 014.

Often alone, Bigga sometimes joins the pod of five involved in last year's attack on a group of eider ducks that were flightless due to moulting.

That pod's big adult male has the number 032 and the name Busta - after Busta Voe. Its smallest member, a three-year-old numbered 067, has just been named Ossa, a location in north-west Mainland Shetland after public suggestions were invited.

With a different pod of eight reported this summer, the orca presence in Shetland is considered greater than in former times - and Mr Foote feels this is supported by an aspect of local folklore.

Shetlanders have special names for prominent local creatures - for instance the great skua, a rare seabird, is known as the bonxie, the black guillemot is the tystie and the common seal, the selkie.

"Perhaps significantly, however, there isn't a Shetland name for the killer whale", said Mr Foote. "That could indicate it has only been appearing regularly in Shetland waters in comparatively recent times."

If that is the case, one possibility is that it is linked to the disappearance of sand-eels from Shetland and Orkney waters since the 1980s.

Killer whales don't feed directly on them but their normal diet covers a range of creatures - sea mammals, birds and larger fish - that do. Has there been a change in hunting patterns due to the food chain disruption caused by the sand-eel absence?

UK National Whale and Dolphin Watch Results 2008

July 2008. The 2008 National Whale and Dolphin Watch produced some interesting results despite bad weather, especially in the north, according to Sightings Officer Edita Magileviciute.


Sixty manned sites were open to the general public, but watches were carried out in more than 165 locations around the country. A total of 339 sightings of whales, dolphins and porpoises were reported during the week, comprising of eight species, and sightings records continue to come in. Bottlenose dolphins were the most frequently seen cetacean with 146 sightings, whilst harbour porpoises were reported 106 times during the week. The third most common cetacean species was the Minke whale with 41 sightings. Other species spotted were Atlantic white-sided dolphin (6 sightings), short-beaked common dolphin (17 sightings), Risso's dolphin (6 sightings), killer whale (10 sightings) as well as a humpback whale.

Harbour porpoises
The results were comparable to previous years with harbour porpoises being the most widely distributed around the British coasts ranging from Orkney to Channel Islands, with concentrations mainly on the east coast of Scotland, Wales and South West of England.

Bottlenose dolphins
Bottlenose dolphins were reported off Northeast Scotland all the way down to the Channel Islands, with the Moray Firth and Southwest Cardigan Bay being the most common locations.

Common dolphins
Short-beaked common dolphins were observed more off the northeast coast of Scotland and Northwest Scotland than in their more regular haunts in South-west England and West Wales.

Minke whales
Minke whale sightings were observed in several areas of Scotland with the major concentration (30% of sightings) in the Northwest of Scotland and Outer Hebrides.

Atlantic white-sided dolphins
Atlantic white-sided dolphins were seen mainly off East Scotland between Aberdeen and Stonehaven. Risso's dolphin sightings ranged from Orkney to Anglesey in North Wales. There were no records from their usual range along the west coast of Scotland or the Isle of Man.

Orca & Humpback
Ninety percent of killer whale sightings were reported from Orkney and Shetland, with more sightings occurred this year than in any previous year of the National Whale & Dolphin Watch. The rarest species sighted was a humpback whale in Catfirth, Shetland.

Wales most popular
The region with the highest reported number of sightings was Wales with 98 sightings. Northeast Scotland had 79 sightings reported. Other regions with high numbers (20 or more) of sightings were Orkney and North Scotland, Cornwall, South Grampian, and North Grampian, Northwest Scotland and Outer Hebrides. Northeast Scotland had the greatest variety of species sighted, with six identified species seen during the week.

Bad weather
Edita said:"The bad weather in some parts of the UK meant that many watches were cancelled or abandoned early. Even when watches were carried out, the sightings rates were down, as the likelihood of seeing cetaceans decreased significantly with poor visibility, rain, fog and high seas. However, In New Quay Bay, West Wales, we observed bottlenose dolphins almost every day despite rain, fog and gusty winds."

Notable sightings from this year's watch include:
• A Risso's dolphin spotted in the River Clyde, close to the centre of Glasgow.
• A group of approximately 100 short-beaked common dolphins in the Sound of Sleat, Inner Hebrides
• Groups of 18-40 short-beaked common dolphins off Caithness and in the Moray Firth, Northeast Scotland.
• Groups of 30-35 killer whales in offshore waters northeast of Shetland.
• A humpback whale in Catfirth, Shetland

Country diary Shetland

My head is filled with unforgettable images of killer whales. Nearby is an offshore rock that is a favourite haul-out for seals - prey for killer whales. That day the rock was abandoned and the seals were in the shallows, hoping these would afford some protection. Upright in the water, heads held as high as possible, they appeared like marine meerkats in their hyper-vigilance.

I think all of us watching gasped aloud when, from the centre of a flurry of water, the small, dark body of a seal was flung spinning through the air. Where it landed there was a commotion of water; the surface seemed to muddy briefly and then bloomed red. Its kill swiftly and efficiently made, the whale resumed circling, while gulls swooped, quarrelling over surface scraps.

The menace of that dorsal fin slicing through the water as the whale maintained its relentless patrolling! The readily available speed as it occasionally heeled into an accelerated turn! The aura of power did not diminish on its rare forays along the coast - the fin was easily visible half a mile away.

Two days later a pod including a calf turned up in exactly the same place. Down on the rocky foreshore we stood in warm sunshine watching them hunt as a group. The blows of their breathing clearly audible, bodies gleaming in the sun, they constantly passed within yards of the spellbound observers, patient, effortless cruising and circling suddenly culminating in an explosion of power and swift motion as a kill was made. Later from the cliff top we watched with awe as they sped, tight-grouped, across the bay, sunlight casting colours through the fine mist of their blows. Intriguingly, it seems the group's arrival may not have been coincidence. The Scottish Killer Whale Project identifies and records orcas, naming them for the place they are first seen. Recognised by his notched dorsal fin, our first visitor was Bigga, who habitually travels alone. He is known to associate with a family group known as the Eynhallow 5 - the group who turned up just two days after he did.

Rare killer whales sighting off Twofold Bay

A pleasure cruise on the New South Wales far south coast has turned into a worldwide scientific find for an Eden couple.

Three months ago, Nick and Helen Haenic took photos of a pod of killer whales off Twofold Bay, but they were not the normal orcas often seen in far south coast waters.

Instead, researchers have identified them as 'type c' antarctic killer whales and this is only the second time they have ever been seen outside cold southern waters.

Sapphire Coast Marine Discovery Centre spokeswoman, Jennie Robb, says it proves the need to make Eden a centre of excellence for marine research.

"This is exactly what we have wanted to see from the very beginning. The idea was we have a lot of local knowledge here," she said.

"We have a lot of people who work on the ocean and recreate on the ocean and they have always said there is something special in this particular body of water."

Killer whale rescued



An orca whale stranded west of Auckland was transported by road today and released off a city beach.

The 3.4-metre juvenile female, estimated to be three years old, was reported at 3pm yesterday to have been beached at Huia.

It was looked after overnight by Project Jonah and Department of Conservation staff.

Department spokesman Bill Trusewich said the whale was small enough to be handled and a decision was made this morning to move it by trailer to Takapuna, on Auckland's North Shore.

The reason for the 43km journey, which took about 90 minutes, was that the water was calmer at Takapuna than at Huia.

Mr Trusewich said the whale didn't take long to get refloated.

"Within 10 minutes it was able to regain its stability again and move off by itself," he said.


As it made its way out to Rangitoto Channel it was being monitored to ensure it did not try to come back ashore or lose its bearings.

The monitoring on the water was done by New Zealand orca researcher Ingrid Visser and Jean-Michel Cousteau, son of the late ocean explorer Jacques Cousteau.


Jean-Michel Cousteau and his son, Fabien, have been in New Zealand shooting footage for a television programme.

Pollution charges laid after oil spill in whale habitat

CAMPBELL RIVER, B.C. -- Pollution charges have been laid in connection with a barge that overturned in a sensitive killer whale reserve off Vancouver Island.

The barge carrying a fuel truck loaded with 10,000 litres of diesel, logging equipment and buckets of hydraulic oil tipped into Robson Bight off Vancouver Island's east coast last August.

A total of 10 charges have been laid against Gowlland Towing, the owner of the barge, Ted LeRoy, the company that hired the barge and Carl Strom, the skipper of the tug towing the vessel.

The charges, including unlawfully discharging oil in an area frequented by fish, have been laid under the Shipping Act, the Migratory Birds Convention Act and the Fisheries Act.

Jennifer Lash, of the environmental group Living Oceans Society, says the charges send a message that companies can't get away with putting B.C. wildlife in danger.

Robson Bight is one of the few spots in the world where killer whales rub their bodies on the pebbles along the beach.

Whale treats TV crew to surprise feast

BBC Springwatch presenter Simon King was given an unexpected treat as he started filming his new series about Shetland wildlife yesterday (Wednesday).

Mr King and his crew, who only arrived in the isles on Sunday, were called to South Nesting Bay where a crowd was gathering to watch a lone killer whale harassing a herd of seals yesterday morning.

Producer Martin Hughes-Games said the team arrived just too late to witness the whale feast on a seal, but watched it for several hours as it cruised in front of about six terrified seals.

“We did manage to film when a couple of seals crept out into the water and suddenly there was all this movement as the whale went powering in, but he missed them. It was very, very exciting,” Mr Hughes-Games said.

To add to their delight, while they were still at Nesting after the whale had left an otter reared its head right in front of the crew.

“Simon is most passionate about otters and blow me down he’s filming one now that just popped up in front of us,” the producer said last night.

Mr King is staying in Shetland on and off with his wife and two year old daughter for the next year at least as he films his six part series Shetland Diary with Simon King, due to be screened in 2010.

“Most of the filming will be done next summer but if it carries on like this perhaps we can bring it forward,” Mr Hughes-Games said.

Mr King appears in public on Saturday (5 July) at Lerwick’s Garrison Theatre to answer questions about his life and work and to launch the first Shetland Nature festival.

As part of the week long event, people are being invited to choose a name for a three year old killer whale calf which has been swimming around Shetland with its family pod for the past few years.

Andy Foote, of the Scottish Killer Whale Project Team, said the young whale was known as calf 067 and its father was called Busta, after Busta Voe where it was spotted, but was unsure of the youngster’s gender. “It is hard to tell if calves are male or female so a name should be suitable for either,” he said.

“We can often work out who the mother of the calf is as young whales often associate most closely with their mother, however 067 has mostly been seen swimming next to 032, who we believe is probably his uncle or big brother, as killer whale groups are usually made up of family members.”
